Application filed November 10, 1919. Y Serial No. 336,921.

To all 'whom it may concern:

Be it known that I, ALnxrs D. PARKER, a citizen of the United States,residing at Villa Nova, in the county of Delaware and Sta-te ofPennsylvania, have invented a certain new and useful Mixing Machine, ofwhich the following is a specification.

The principal object of the present invention is to provide a machinefor successfully mixing and feeding an agglomeration of line material,as pulverulent coal, and a binder, as a mixture or emulsion of mineraloil and a vegetable paste and water.

The invention willbe claimed at the end hereof, but will be firstdescribed in connection with the embodiment of it chosen from otherembodiments for the sake of illustration in the accompanying drawingsforming part hereo-f aud in which*- Figure l, is a top or plan view ofso much of a mixing machine as is necessary for illnstrating anembodiment of the invention.'

F ig. 2, is a sectional view taken on the line 2 2, of Figure 1, lookingin the direction of the arrows, and y Figs. 3 and 4,- are detachedperspective views illustrating a detail of construction vided in themargin of the flights of the conveyer. As indicated on the drawings thenotches 3, are spaced ninety degrees apart. 4, are blades shown asrectangular and they extend from the side wall of the notches for wardin the direction of feed of the conveyer. The blades 4, are attached toor bent up from the conveyer and they are shown as arranged on theleading sides of the notches 3, leaving the material, or more accuratelysome of it, free to pass through the notches and be .carried andvstirred by the blades. The area of the notches and the area of theblades are substantially the same, although the latter may besufficiently Smaller to provide clearance.

The described pro-visionv of notches-and blades not only improves themixing operation, as has been. indicated, but also clears the conveyerand facilitates the feed, so that the machine works continuously andaffords a thorough mixture. i

Modification may be made in details of construction and arrangement andtherefore the invention is not limited as to such matters or otherwisethan as theI prior art and the appended claims may require.

I claim: l. In a machine for mixing coal briquettes materialsand thelike consisting of a trough and a screw conveyer the combination withangularly spaced notches provided in the margin of the flights of the.conveyer, of blades extending from a side wall of the notches forward inthe direction'of feed of the conveyer.

2. In a machine vfor mixing coal briquettes materials and the likeconsisting of a trough and a screw conveyer the combination with notchesprovided in the margin ofthe flights of the conveyer of blades extendingfrom the flights forward in the direction of feed.

23. In a machine for mixing coal briqucttes materials and the like'consistingof a trough and a screw conveyer the combination withArectangular notches provided in the margin of the flights of theconveyor of rectangular blades of substantially the same area as thenotches extending forward in the direction of feed.
